I have tried to install Let’s Encrypt with updated Plesk for a domain and its 4 domain aliases and I get the following error:
Detail: Fetching http://mydomain.com/.well-known/acme-challenge/yVxSQq72CgfrOYlhocfxdUj1vdnJYjCR01B3IH9Z4ns: Connection refused
It works when I install only for the main domain.
My web server is a Centos 7 with Apache.
Thank you very much. I’m going crazy with this issue.
